Convex free tier includes Reactive backend — 1M function calls/month, 0.5 GB database + vector storage, 1 GB file storage… Not verified — our last read, on 2026-10-07, found the same terms as an earlier read we had declined to record. Compare with 8 alternatives in Databases.
Subtypes in Databases: backend_platform — bundles a database with auth, functions or storage as one product. We read that on 2026-08-31 from https://www.convex.dev/, where it says: “Convex is the reactive backend platform that keeps up with you and your agents.” How we use this.

No recorded pricing changes for Convex. We publish no change we refused to record, so treat the empty history as a statement about our records, not about this vendor's pricing.
How Convex compares against every one of the 8 we list, not against a selection of them. A surface with room for every member of a tied set may rotate their order. A surface with room for only some of them names none of them, because which ones it named would be the claim, and a claim seeded on the date is not the one we serve tomorrow. How we decide this.
